DETAILED DESCRIPTION

In wireless communications, the architecture of the General Packet Radio Service (GPRS) relies on circuit-switching. That is, circuits are established between the calling parties throughout the telecommunication network. To facilitate more flexible data transmissions, packet-switching is added to circuit-switching so that data is transported in packets without the establishment of dedicated circuits. Because packet-switching offers more flexibility and efficiency, the Internet Protocol (IP) is used in Fourth-Generation (4G) Long-Term Evolution (LTE) systems as the protocol to transport all services, eliminating the need for separate circuit domain and packet domain. FIG. 1 illustrates an example architecture of Evolved Packet Core (EPC) 100 in LTE communication systems. As shown in FIG. 1 , a User Equipment (UE) 101 is connected to the EPC over an access network (e.g., the Evolved Universal Mobile Telecommunication Service Terrestrial Radio Access Network, E-UTRAN) 103 that includes one or more base stations (eNodeB) 105. The EPC 107 comprises four main elements: the Serving Gateway (SGW) 112, the Packet Data Network Server (PGW) 114, the Mobility Management Entity (MME) 116, and the Home Subscriber Server (HSS) 118. In particular, the PGW 114 is the gateway server that routes packets to and from the Packet Data Network (PDN). The PGW 114 also performs various other functions such as IP allocation or policy control.

With the advancement in wireless technologies, the 5G/New Radio (NR) wireless protocol can support data connectivity and services enabling deployments. In particular, the 5G core (5GC) network architecture enables a separation of the gateway functions into control plane (CP) and user plane (UP). The CP and UP separation (also referred to CP-UP split) allows for flexible deployment of UP separate from the CP and enables UP distribution and edge breakout of traffic already in the EPC. For example, separate PDN connections can use different PGW-U/PGW-Us in central and local deployments.

During the migration period when NR coverage is expanding, services requiring wide-area coverage are best supported through interworking between the 5G Core (5GC) and the existing Evolved Packet Core (EPC). To enable IP address preservation when connecting over and changing between 4G and 5G access, the 5GC architecture includes a common UP anchor point (e.g., by the session management function (SMF) plus packet data network gateway control plane function (SMF+PGW-C) and the user plane function (UPF) plus PGW user plane function (UPF+PGW-U). FIG. 2 illustrates an example of EPS-5GC interworking in accordance with the present technology.

As the wireless technologies evolve, capabilities of the user devices also evolve at the same time. To provide simultaneous support for multiple generations of technologies (e.g., 4G/LTE, 5G/NR, and other future generations of wireless technologies), a network deployment needs to support newer and legacy devices at the same time. For example, as shown in FIG. 2 , a UE that has both 4G/LTE and 5G/NR capabilities can be anchored to either the LTE PGW 201 via the E-UTRAN or the 5G UPF+PGW-U 203 via the New Generation Radio Access Network (NG-RAN). In some embodiments, it is desirable for a network operator to anchor a user device to certain packet gateways according to the device capabilities. For example, anchoring the 5G-capable device to UPF+PGW-U for 5GC can minimize communication latency, thereby providing better user experiences for the user.

User devices are often provisioned on a per-user basis by network operators. That is, under the Domain Name Server (DNS) resolution mechanism, a user can be provisioned with a set of unique Access Point Names (APNs) for the associated devices so that data sessions using these APNs can be anchored on corresponding PGWs. However, a user can have devices with different capabilities (e.g., devices that support 3G and/or LTE technologies only, and devices that support 5G). When the user changes from an LTE device to a 5G device to access the network, the data sessions anchored on a previous set of gateways (e.g., PGWs for EPC) cannot provide optimal connections for the 5G device.

This patent document discloses techniques that can be implemented in various embodiments to allow flexible selections of gateway servers to anchor the user devices to appropriate gateway servers according to device capabilities. The disclosed techniques introduce minimal changes to the existing provisioning mechanism and DNS resolution framework, while enabling optimal connections and providing better user experiences.

FIG. 3 is a flowchart representation of a method 300 for wireless communication in accordance with one or more embodiments of the present technology. The method 300 includes, at operation 310, provisioning multiple wireless electronic devices of a user with a first access point name (APN). For example, the wireless electronic devices of the user can be provisioned with a generic data APN (e.g., internet.domain.com) when the user signs up for service. In some embodiments, the generic data APN is not associate with any access technologies. That is, the generic data APN serves as a placeholder for the user. The actual APNs that are used to anchor the data sessions are determined subsequently in part based on the capabilities and user's devices. In some embodiments, the generic data APN can correspond to a first gateway server associated with a first radio access technology (e.g., a default gateway server with a default access technology). For example, the generic data APN can correspond to the PGW in EPC for LTE wireless communications.

The method 300 includes, at operation 320, receiving, from a wireless electronic device of the user, a request for establishing a data session. Once the user is provisioned with the first APN (e.g., the generic data APN), all requests from the user for a data session are associated with the first APN initially. In some embodiments, the multiple wireless electronic devices of the user have different capabilities. For example, some of the electronic devices of the user have 4G capabilities while some of the wireless electronic devices of the user can have both 4G and 5G capabilities. The network can maintain a list of alternative or alias APNs that are mapped to the capabilities of the devices of the user and/or the corresponding access technologies. In some embodiments, the capability of the wireless electronic device is indicated based on a unique identifier of the device. The capability of the wireless electronic device can indicate a radio access technology that is supported by the wireless electronic device. For example, the International Mobile Equipment Identify (IMEI) of the device can be used to identify the device capabilities. Table 1 shows an example mapping of the device IMEI, the radio access technologies (RATs), and alias APNs.

TABLE 1 Device Identifier RAT Alias APN IMEI range A (e.g. 2G/3G 2G aliasAPN1.domain.com capable devices) IMEI range A (e.g. 2G/3G 3G aliasAPN2.domain.com capable devices) IMEI range B (e.g. 4G only 4G aliasAPN3.domain.com devices) IMEI range C (e.g. 4G/5G 4G aliasAPN3.domain.com devices) IMEI range C (e.g. 4G/5G 5G aliasAPN4.domain.com devices)

The method 300 includes, at operation 330, determining, in part based on a capability of the wireless electronic device, a second access point name that is different from the first access point name. Given the request from specific device of the user and the list of alias APNs, the network can use the IMEI of the device to determine which alias APN is to be used for the selection of the packet gateway.

In some embodiments, the determining of the second access point name is also based on the access technology over which the request is received. For example, the IMEI of a device is within the range C, which indicates that the device supports both 4G and 5G capabilities. The request from the device is received using the 4G RAT. Therefore, the alias APN to be used for the data session is aliasAPN3.domain.com for 4G communications. As another example, the IMEI of another device is also within the range C for both 4G and 5G capable devices. The request from the device is received using the 5G RAT. Therefore, the alias APN to be used for the data session is aliasAPN4.domain.com for 5G communications.

In some embodiments, the determining of the second access point name is further based on load balancing of the network. For example, the IMEI of a device is within the range C, which indicates that the device supports both 4G and 5G capabilities. The network determines that the EPC carries a load of 20% and the 5GC carries a load of 80%. A PWG in the EPC can be selected to establish the data session to avoid potentially service latency caused by the heavy load of 5GC. Therefore, the alias APN to be used for the data session is aliasAPN3.domain.com for LTE communications.

In some embodiments, the determining of the second access point name can be based on specific device families. For example, a specific APN aliasAPN1.domain.com can be assigned to Android devices with 2G/3G capacities. A different APN aliasAPN2.domain.com can be assigned to iOS devices with the same 2G/3G capabilities. A third APN aliasAPN3.domain.com can be assigned to iOS devices with different capacities (e.g., 4G or 5G capabilities).

The method 300 includes, at operation 340, selecting a second packet gateway server corresponding to the capability of the wireless electronic device using the second access point name. Once the alias APN is determined, a DNS query can be performed using the alias APN as opposed to the initially provisioned generic data APN from the device. The IP address of the selected packet gateway server can be returned in the DNS response. It is noted that the use of alias APNs imposes no changes in the existing DNS framework. That is, the DNS queries and responses can be agnostic about the generic data APN and the alias APNs. Specific information regarding the device capabilities and/or RATs can thus be hidden from the DNS framework and does not result in any additional DNS queries. In some embodiments, when changes to the existing DNS entries are allowed, the DNS query can include a part of the device IMEI, such as the Type Allocation Code (TAC). The TAC can be used to identify a particular model and/or a revision of the device so that specific gateway can be selected based on device families.

In some embodiments, the second packet gateway server is associated a second radio access technology that is different than the first radio access technology. For example, given the alias APN aliasAPN4.domain.com, a PGW-U for 5GC can be selected for the device that is capable of handling both 4G and 5G communications. Here, the second RAT (e.g., 5G RAT) is different than the default RAG (e.g., 4G RAT) for the generic data APN for the user.

The method 300 also includes, at operation 350, establishing the data session between the second packet gateway server and the wireless electronic device. Given the IP address in the DNS response, the data session can be established accordingly. The user device is now provided with connecting to the network via the data session to transmit and/or receive data.

CONCLUSION

As noted above, the disclosed techniques can be implemented, with minimal changes to the existing DNS framework, to select appropriate gateway servers to anchor data traffic for user devices based on device capabilities. For devices with better capabilities (e.g., 5G capable devices), appropriate packet data gateways can be used to minimize service latency and delay, thereby providing better overall user experiences to the user. Based on the existing per-user provisioning mechanism, the disclosed techniques allow flexible gateway determinations for different devices of the same user.

FIG. 4 is a diagrammatic representation of a machine in the example form of a computer system 400 within which a set of instructions, for causing the machine to perform any one or more of the methodologies or modules discussed herein, can be executed. In the example of FIG. 4 , the computer system 400 includes a processor, memory, non-volatile memory, and a network communication interface device. Various common components (e.g., cache memory) are omitted for illustrative simplicity. The computer system 400 is intended to illustrate a hardware device on which any of the components described in the example of FIGS. 1-8 (and any other components described in this specification) can be implemented. The computer system 400 can be of any applicable known or convenient type. The components of the computer system 400 can be coupled together via a bus or through some other known or convenient device.

This disclosure contemplates the computer system 400 taking any suitable physical form. As example and not by way of limitation, computer system 400 can be an embedded computer system, a system-on-chip (SOC), a single-board computer system (SBC) (such as, for example, a computer-on-module (COM) or system-on-module (SOM)), a desktop computer system, a laptop or notebook computer system, an interactive kiosk, a mainframe, a mesh of computer systems, a mobile telephone, a personal digital assistant (PDA), a server, or a combination of two or more of these. Where appropriate, computer system 400 can include one or more computer systems 400; be unitary or distributed; span multiple locations; span multiple machines; or reside in a cloud, which can include one or more cloud components in one or more networks. Where appropriate, one or more computer systems 400 can perform without substantial spatial or temporal limitation one or more steps of one or more methods described or illustrated herein. As an example and not by way of limitation, one or more computer systems 400 can perform in real time or in batch mode one or more steps of one or more methods described or illustrated herein. One or more computer systems 400 can perform at different times or at different locations one or more steps of one or more methods described or illustrated herein, where appropriate.

The processor can be, for example, a conventional microprocessor such as an Intel Pentium microprocessor or Motorola power PC microprocessor. One of skill in the relevant art will recognize that the terms “machine-readable (storage) medium” or “computer-readable (storage) medium” include any type of device that is accessible by the processor.

The memory is coupled to the processor by, for example, a bus. The memory can include, by way of example but not limitation, random access memory (RAM), such as dynamic RAM (DRAM) and static RAM (SRAM). The memory can be local, remote, or distributed.

The bus also couples the processor to the non-volatile memory and drive unit. The non-volatile memory is often a magnetic floppy or hard disk, a magnetic-optical disk, an optical disk, a read-only memory (ROM), such as a CD-ROM, EPROM, or EEPROM, a magnetic or optical card, or another form of storage for large amounts of data. Some of this data is often written, by a direct memory access process, into memory during execution of software in the computer 400. The non-volatile storage can be local, remote, or distributed. The non-volatile memory is optional because systems can be created with all applicable data available in memory. A typical computer system will usually include at least a processor, memory, and a device (e.g., a bus) coupling the memory to the processor.

Software is typically stored in the non-volatile memory and/or the drive unit. Indeed, storing and entire large program in memory can not even be possible. Nevertheless, it should be understood that for software to run, if necessary, it is moved to a computer readable location appropriate for processing, and for illustrative purposes, that location is referred to as the memory in this paper. Even when software is moved to the memory for execution, the processor will typically make use of hardware registers to store values associated with the software, and local cache that, ideally, serves to speed up execution. As used herein, a software program is assumed to be stored at any known or convenient location (from non-volatile storage to hardware registers) when the software program is referred to as “implemented in a computer-readable medium.” A processor is considered to be “configured to execute a program” when at least one value associated with the program is stored in a register readable by the processor.

The bus also couples the processor to the network interface device. The interface can include one or more of a modem or network interface. It will be appreciated that a modem or network interface can be considered to be part of the computer system 400. The interface can include an analog modem, ISDN modem, cable modem, token ring interface, satellite transmission interface (e.g., “direct PC”), or other interfaces for coupling a computer system to other computer systems. The interface can include one or more input and/or output devices. The I/O devices can include, by way of example but not limitation, a keyboard, a mouse or other pointing device, disk drives, printers, a scanner, and other input and/or output devices, including a display device. The display device can include, by way of example but not limitation, a cathode ray tube (CRT), liquid crystal display (LCD), or some other applicable known or convenient display device. For simplicity, it is assumed that controllers of any devices not depicted in the example of FIG. 5 reside in the interface.

In operation, the computer system 400 can be controlled by operating system software that includes a file management system, such as a disk operating system. One example of operating system software with associated file management system software is the family of operating systems known as Windows® from Microsoft Corporation of Redmond, Wash., and their associated file management systems. Another example of operating system software with its associated file management system software is the Linux™ operating system and its associated file management system. The file management system is typically stored in the non-volatile memory and/or drive unit and causes the processor to execute the various acts required by the operating system to input and output data and to store data in the memory, including storing files on the non-volatile memory and/or drive unit.

Some portions of the detailed description can be presented in terms of algorithms and symbolic representations of operations on data bits within a computer memory. These algorithmic descriptions and representations are the means used by those skilled in the data processing arts to most effectively convey the substance of their work to others skilled in the art. An algorithm is here, and generally, conceived to be a self-consistent sequence of operations leading to a desired result. The operations are those requiring physical manipulations of physical quantities. Usually, though not necessarily, these quantities take the form of electrical or magnetic signals capable of being stored, transferred, combined, compared, and otherwise manipulated. It has proven convenient at times, principally for reasons of common usage, to refer to these signals as bits, values, elements, symbols, characters, terms, numbers, or the like.

It should be borne in mind, however, that all of these and similar terms are to be associated with the appropriate physical quantities and are merely convenient labels applied to these quantities. Unless specifically stated otherwise as apparent from the following discussion, it is appreciated that throughout the description, discussions utilizing terms such as “processing” or “computing” or “calculating” or “determining” or “displaying” or “generating” or the like, refer to the action and processes of a computer system, or similar electronic computing device, that manipulates and transforms data represented as physical (electronic) quantities within the computer system's registers and memories into other data similarly represented as physical quantities within the computer system memories or registers or other such information storage, transmission or display devices.

The algorithms and displays presented herein are not inherently related to any particular computer or other apparatus. Various general purpose systems can be used with programs in accordance with the teachings herein, or it can prove convenient to construct more specialized apparatus to perform the methods of some embodiments. The required structure for a variety of these systems will appear from the description below. In addition, the techniques are not described with reference to any particular programming language, and various embodiments can thus be implemented using a variety of programming languages.

In alternative embodiments, the machine operates as a standalone device or can be connected (e.g., networked) to other machines. In a networked deployment, the machine can operate in the capacity of a server or a client machine in a client-server network environment, or as a peer machine in a peer-to-peer (or distributed) network environment.

The machine can be a server computer, a client computer, a personal computer (PC), a tablet PC, a laptop computer, a set-top box (STB), a personal digital assistant (PDA), a cellular telephone, an iPhone, a Blackberry, a processor, a telephone, a web appliance, a network router, switch or bridge, or any machine capable of executing a set of instructions (sequential or otherwise) that specify actions to be taken by that machine.

While the machine-readable medium or machine-readable storage medium is shown in an exemplary embodiment to be a single medium, the term “machine-readable medium” and “machine-readable storage medium” should be taken to include a single medium or multiple media (e.g., a centralized or distributed database, and/or associated caches and servers) that store the one or more sets of instructions. The term “machine-readable medium” and “machine-readable storage medium” shall also be taken to include any medium that is capable of storing, encoding or carrying a set of instructions for execution by the machine and that cause the machine to perform any one or more of the methodologies or modules of the presently disclosed technique and innovation.

In general, the routines executed to implement the embodiments of the disclosure, can be implemented as part of an operating system or a specific application, component, program, object, module or sequence of instructions referred to as “computer programs.” The computer programs typically comprise one or more instructions set at various times in various memory and storage devices in a computer, and that, when read and executed by one or more processing units or processors in a computer, cause the computer to perform operations to execute elements involving the various aspects of the disclosure.

Moreover, while embodiments have been described in the context of fully functioning computers and computer systems, those skilled in the art will appreciate that the various embodiments are capable of being distributed as a program product in a variety of forms, and that the disclosure applies equally regardless of the particular type of machine or computer-readable media used to actually effect the distribution.

Further examples of machine-readable storage media, machine-readable media, or computer-readable (storage) media include but are not limited to recordable type media such as volatile and non-volatile memory devices, floppy and other removable disks, hard disk drives, optical disks (e.g., Compact Disk Read-Only Memory (CD ROMS), Digital Versatile Disks, (DVDs), etc.), among others, and transmission type media such as digital and analog communication links.

In some circumstances, operation of a memory device, such as a change in state from a binary one to a binary zero or vice-versa, for example, can comprise a transformation, such as a physical transformation. With particular types of memory devices, such a physical transformation can comprise a physical transformation of an article to a different state or thing. For example, but without limitation, for some types of memory devices, a change in state can involve an accumulation and storage of charge or a release of stored charge. Likewise, in other memory devices, a change of state can comprise a physical change or transformation in magnetic orientation or a physical change or transformation in molecular structure, such as from crystalline to amorphous or vice versa. The foregoing is not intended to be an exhaustive list in which a change in state for a binary one to a binary zero or vice-versa in a memory device can comprise a transformation, such as a physical transformation. Rather, the foregoing is intended as illustrative examples.

A storage medium typically can be non-transitory or comprise a non-transitory device. In this context, a non-transitory storage medium can include a device that is tangible, meaning that the device has a concrete physical form, although the device can change its physical state. Thus, for example, non-transitory refers to a device remaining tangible despite this change in state.

Unless the context clearly requires otherwise, throughout the description and the claims, the words “comprise,” “comprising,” and the like are to be construed in an inclusive sense, as opposed to an exclusive or exhaustive sense; that is to say, in the sense of “including, but not limited to.” As used herein, the terms “connected,” “coupled,” or any variant thereof means any connection or coupling, either direct or indirect, between two or more elements; the coupling or connection between the elements can be physical, logical, or a combination thereof. Additionally, the words “herein,” “above,” “below,” and words of similar import, when used in this application, refer to this application as a whole and not to any particular portions of this application.

Aspects of the invention can be modified to employ the systems, functions, and concepts of the various references described above to provide yet further implementations of the invention.

These and other changes can be made to the invention in light of the above Detailed Description. While the above description describes certain examples of the invention, and describes the best mode contemplated, no matter how detailed the above appears in text, the invention can be practiced in many ways. Details of the system may vary considerably in its specific implementation, while still being encompassed by the invention disclosed herein.
